Step-by-step explanation:
A term is a number, a variable, or a constant multiplied by a variable or variables.
Like terms are terms that contain the same variables raised to the same power. Only the numerical coefficients are different.
A coefficient is a multiplicative factor in some term of a polynomial (expression).
Constant is a term in the algebraic expression that contain only number.
n + 5n = n + 5n + 0
terms: n, 5n
like terms: n, 5n
coefficients: 1, 5
constant: 0
simplified form: n + 5n = 6n
term: 6n
coefficient: 6
constant: 0
=======================
12c - c = 12c - c + 0
terms: 12c, -c
like terms: 12c, -c
coefficients: 12, -1
constant: 0
simplified form: 12c - c = 11c
term: 11c
coefficient: 11
constant: 0
========================
-4j - 1 - 4j + 6
terms: -4j, -1, -4j, 6
like terms: -4j, -4j and -1, 6
coefficients: -4, -4
constants: -1, 6
simplified form: -4j - 1 - 4j + 6 = (-4j - 4j) + (-1 + 6) = -8j + 5
term: -8j, 5
coefficient: -8
constant: 5
<span>A line graph is used to show a trend
over a period of time. It is plotted as a series of points,
which are then joined with straight lines. The ends of the line graph do not have to join to the axes.
</span><span>A scatter plot is a type of plot
or mathematical diagram using Cartesian coordinates to display values
for typically two variables.
The difference between a line graph and a scatter plot is that a</span><span> line graph presents continuous and linked data, while a scatter plot presents unlinked data.</span>
A regular polygon can be any shape with all equal side lengths and equal angle measurements.
So, yes. It can be a regular polygon.
Hope this helps! <3
Answer:
False
Step-by-step explanation:
first step is
x+y = 30
x-y = 12
